Investors seek greater clarity on Tonbo’s critical components, foreign sourcing and related-party procurement.
New Delhi: Tonbo Imaging’s proposed IPO comes at a time when India’s push for self-reliance in defence is creating significant investor interest in home-grown defence-technology companies. While Tonbo has positioned itself as an Indian developer and manufacturer of advanced military imaging and targeting systems, investors need a clearer understanding of what sits behind those products—most importantly, the origin of critical components, the company’s overseas procurement relationships and the extent to which its supply chain is genuinely indigenous.
Tonbo describes itself as an original equipment manufacturer developing electro-optical, thermal-imaging, targeting, surveillance and guidance systems for military applications. Its technology credentials may be significant. But its procurement structure, particularly its links to Singapore and China, warrants greater transparency before the company enters public markets.
At the centre of the issue is CEAQ Technologies Pte Ltd, a Singapore company formerly known as Tonbo Imaging Pte Ltd. Tonbo’s IPO documents identify CEAQ Singapore as an enterprise having substantial interest in the company. It holds 26.77% of Tonbo Imaging India, while CEAQ Technologies Private Limited, the Indian group entity formerly known as Tonbo Imaging Private Limited, holds another 17.74%. Together, the two entities account for more than 44% of the company before the offer.
CEAQ Singapore is also part of Tonbo’s commercial ecosystem. Tonbo’s filings disclose related-party transactions involving purchases of project material and equipment from the Singapore entity. This raises an important question for investors: what exactly is being purchased, where was it manufactured, and at what price?
Trade databases provide another reason for scrutiny. Volza records more than 11,500 import shipments into Tonbo Imaging India from 226 suppliers, including about 2,262 shipments attributed to China. That represents roughly 19.65% of recorded shipments by count—not procurement value. Chinese optics companies, including Changchun Jstar Optics and Changchun Sunday Optoelectronics, also appear in the trading records. CEAQ Singapore itself has been identified in trade records as an exporter to Tonbo India.
Separately, recent reporting on Tonbo’s revised DRHP says allegations were disclosed concerning procurement of critical components from Chinese OEMs through CEAQ Singapore. The allegations also questioned whether certain contracts were won below raw-material cost to make the order book appear stronger. Tonbo has denied the allegations. Public trade databases do not, by themselves, establish every China-to-CEAQ-to-Tonbo transaction. That distinction is important.
But precisely because these allegations have been raised, transparency matters.
Tonbo’s earlier DRHP disclosed an order book of about ₹266.57 crore comprising 36 firm orders. Yet an order book is meaningful only if investors understand the economics behind it. Tonbo’s operating revenue rose to about ₹469.08 crore in FY25 from ₹428.19 crore in FY24, but fell to approximately ₹362.65 crore in FY26. PAT declined from about ₹72.76 crore to ₹50.88 crore.
The proposed IPO is also entirely an Offer for Sale of about 18.09 million shares. The company will receive no fresh capital from the issue. CEAQ Technologies Private Limited is offering about 10.16 million shares and CEAQ Singapore about 4.90 million shares.
None of this proves wrongdoing. Nor does foreign sourcing automatically undermine an Indian defence company. Modern defence manufacturing can involve global supply chains.
But investors deserve to know what lies inside those systems.
Before the IPO, Tonbo should provide clear, verifiable information on the origin of critical components, its procurement from CEAQ, related-party pricing, major suppliers, country-of-origin documentation and the margins on significant contracts.
SEBI must ensure investors receive a complete picture, while the Ministry of Defence should establish whether critical defence systems supplied to the armed forces contain sourcing vulnerabilities that require examination.
The principle is simple: investors should not have to reconstruct a defence company’s supply chain from trade databases and allegations. Tonbo may well be a valuable Indian defence-technology company. But before the public is asked to invest in that story, the company should provide the documents and disclosures necessary to show exactly how Indian—and how independent—its supply chain really is.
